Sewing machine handle operated threading device

Abstract

A sewing machine is provided with a carrying handle movably received at the housing and connected with at least one thread guiding element. The thread guiding element is arranged so that the work to be performed on the sewing machine is favored by its position and access to the carrying handle is not hindered even in the threaded state. The thread guiding element is moved with the carrying handle by a drive mechanism associated with the carrying handle when the handle is moved from an inactive position in the housing to its carrying position the thread guiding element executes a relative movement thereto from its sewing position to its threading position.

I claim: 
     
       1. A sewing machine comprising a sewing machine housing, a carrying handle movably mounted on said housing, at least one thread guiding element movably positioned on said housing, and a drive mechanism associated with said handle and said thread guiding element and effective upon movement of said handle from an inactive inclined position to an upright carrying position to move said thread guiding element from a recessed position to a projecting threading position. 
     
     
       2. A sewing machine according to claim 1 wherein said drive mechanism includes an arm pivotally mounted on said sewing machine and connected to said handle and having a lever portion engageable with a tappet of said thread guiding element for moving said thread guiding element with movement of said handle. 
     
     
       3. A sewing machine according to claim 1 wherein said handle is pivotally mounted on said housing and said guiding element is pivotally connected to said handle. 
     
     
       4. A sewing machine according to claim 1 wherein said thread guiding element has a plurality of thread guides along its length including a guide plate portion and a tensioning device. 
     
     
       5. A sewing machine according to claim 1, wherein said carrying handle includes an underside with a deflecting portion and said thread guiding element has guide portions over said deflection portion and including pins forming tensioning devices on said thread guiding elements. 
     
     
       6. A sewing machine according to claim 1 wherein said thread guiding element comprises an elongated strap member. 
     
     
       7. A sewing machine according to claim 1 wherein said housing has guide slots therein for the passage of thread. 
     
     
       8. A sewing machine according to claim 1 wherein said housing has a front face with a plurality of cut out openings and guide slots contiguous thereto for receiving thread tensioning devices, said tensioning devices comprising at least one pair of rotary opposed tensioning disks. 
     
     
       9. A sewing machine according to claim 1, wherein the underside of said carrying handle is located below said thread guides and below horizontal support pins or thread tensioning devices to deflect the passing thread. 
     
     
       10. A sewing machine according to claim 1, wherein said carrying handle includes an underside with a deflecting portion below said thread guiding elements and below rotary opposed tensioning disks for deflecting threads downwardly. 
     
     
       11. A sewing machine according to claim 4, wherein said tensioning device comprises a plurality of separate deflection plates, one of said plurality of deflection plates being provided on one side of each of said thread guide elements respectively and having a spring biasing thread against an associated said thread guide. 
     
     
       12. A sewing machine according to claim 11 wherein a plurality of hold back cams are provided, each hold back cam being positioned on one side of each of said separate deflection plates and said spring being fastened to said thread guide element.
